Y

Should it be desired to obtain but one grade of sand or a plurality of grades less than the number o separating vunits in themachine, the launder may be moved to feed the material adjacent the second or third wheel as` the case may be, and thereby eliminate the other wheels from the operation. The overflow holes corresponding with the idle wheels, through which foreign matter is removed, may be plugged at the saine time as stated hereinbefore. Any suitable means, such as illustratedV in Fig. 2 of the drawings, may be employed for shifting the launder longitudinally of thebox to any desiredextent,

n weights,

- VInasmuch as the sands settle in the box at ratesy corresponding withYA their different the heavy sandsthat settle shortly after the material has enteredr the box ahead by separate pended of the finer sands, are bailed out of the box the first wheel adjacent the feed-point,

from the lighter sands that aresus- The ner sands movingwith the waterl toout.

i The three wheels deliver the loads of their buckets outside the box, in separate launders,

` bins or other receptacles not shown in the of theniachine as herein described, the sands drawings.

- It will be apparent that in the operation vare kdelivered in a substantially dry condition owing to the slanting 4position of the wheelsthat causes the water to drain from the ybuckets whileY the solids are held in place bythe apron. f

All floating matter such as f leaves and sticks are removed by the overflow. The

' sands delivered by the wheels are automat-v ically separated in different degrees of fine-y ness, or sand of any desired grade of fine-` ness may; be removed from the material by itself by adjustment of the feed-launder.'

" The capacity of the machine may be de-V .creasedor increased by varying the number of the separating units, to deliver any deksired grades of sands, regardless of the j amount of'water fed into the box, and it will *be seen thaty the machine dehydrates, classifiesand cleans the' sands in one operation.

It is to be understood that variations in the form, yconstruction or arrangement of the various elements comprised in the machine, may be resorted to within the scope of va plurality of rotar `ing peripheral buckets in a in the water at higher elevations.'

the invention Yas defined in the hereunto appended claims. Y Y

What I claim and desire to secure by Letters Patent is: f Y l. In a sand-washer, Ya box providing an unobstructed flow of material fed into the box at one end, to the other end ofthe same,

bailing wheels mounted in successive or er between the ends of the box, each of said wheels having peripheral buckets open in a face at right angles to its axis of rotation,-and each wheel being slantingly'disposed so that its said face overhangs aside ofthe box for the discharge of sand. outside the same, an adjustable launder for feeding matter into the box, either at the vfeedend ofthe box, or in advance of any selected number of the wheels whereby to exclude the feed from the other Wheels, and means for shifting said launder longitudinally of the box to any desired extent.

- 2.- In a sand-washer a box having an overflow, a rotary bailing-wheel in the box havface VVat right angles to its axis of rotation, the wheel being slantingly disposed so that its said face overhangs a side of the box for the discharge of sand outside the same, and means for regulating the capacity kof the overflow.

3. In sand-washer, a box providing an unthe other, a succession of rotary bailing wheels in the box, each having peripheral buckets open in a face at right angles to its axis of rotation, and each wheel being slantingly disposed so that its said face overhangs a side of the box for the discharge of sand outside the same, the box having an overflow for water adjacent each wheel, an adjustable launder for feeding material into the box either at an end thereof'or in advance of any selected number of the wheels, whereby to exclude the feed' from the other wheels, means for shifting the said launder longitudinally of the box to any desired ex-y Vobstructed flow of material from one end to y to its axis of rotation, the Wheel being slantingly disposed so that its said face overhangs the said vertical wall of the box for discharging sandv outside the same, a bracket secured to said wall and provided at the inner face of the same with an Vinclined support,

ing portion, and an inclined apron secured to the supporting portion of said bracket and covering a portion of the face of the wheel to prevent the discharge of sand into the box i and projecting over the top of the said vertical wall. f

In testimony whereof I have alhxed my signature.

GEORGE W. COLE.
